Description

Liquid level probe blowing device of impregnator
Technical Field
The invention relates to the technical field of impregnators, in particular to a liquid level probe blowing device of an impregnator.
Background
In a 1140kg/h carbon dioxide expanded tobacco production line, an impregnator is main process equipment for tobacco shred expansion, the tobacco shreds are soaked in carbon dioxide liquid with certain pressure in the impregnator, so that the carbon dioxide liquid can be fully soaked into tobacco shred cell tissues, and then the carbon dioxide liquid in the tobacco shred cell tissues is converted into dry ice (solid) by means of liquid drainage, pressure reduction and the like, so that dry ice tobacco shreds are formed.
When the impregnator is in a filling step, in order to control the filling amount of the carbon dioxide, three liquid level holes, namely a low liquid level hole, a middle liquid level hole and a high liquid level hole, are arranged in the impregnator, and the control mode is that temperature probes are arranged in the low liquid level hole, the middle liquid level hole and the high liquid level hole, and the liquid level detection is realized by detecting the temperature through the temperature probes by utilizing the low-temperature property of the carbon dioxide liquid. In a 1140kg/h carbon dioxide expanded tobacco production line, when carbon dioxide liquid is filled into an impregnator, the liquid filling is stopped when the temperature of low and medium liquid levels is lower than-2 ℃, after tobacco shreds are soaked for a certain time, the impregnator discharges the carbon dioxide liquid into a process tank, the air pressure in the impregnator is discharged through primary pressure discharge and secondary pressure discharge, then the bottom cover of the impregnator is opened, and the tobacco shreds enter the next working procedure.
In the tobacco shred dipping process, impurities such as tobacco powder, smoke dust and the like in the tobacco shred can float on the carbon dioxide liquid level, partial tobacco powder and smoke dust can float at the liquid level probe hole due to the fact that the carbon dioxide liquid level and the middle liquid level hole are basically horizontal, when the tobacco shred dipping step is finished, after carbon dioxide liquid is recovered and carbon dioxide gas is discharged, the lower bottom cover of the dipping device is opened, rapid changes of temperature and pressure can possibly form partial tobacco powder, smoke dust and carbon dioxide to be frozen and remain in the liquid level probe hole, and the temperature probe or the liquid level hole is blocked. When the next pot is produced, the temperature probe can not contact carbon dioxide liquid, the liquid level judgment is wrong due to inaccurate temperature measurement, and V23 liquid adding weight and a liquid level switch are generated to alarm, so that the equipment is stopped, and the production is stopped. Meanwhile, the temperature probe needs to be manually disassembled to manually blow the liquid level hole, so that the production efficiency is seriously influenced, and the risk of material breakage in production also exists.
